NUMBERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 245,220, dated August2, 1881.

Application filed February 19, 1881.

To all whom it may concern Be it known that I, WILLIAM ROBINSON, acitizen of the United States, residing at Vashington, in the county ofWashington and Distriet of Columbia, have invented certain new anduseful Improvements in Numbering-Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters or figures of reference marked thereon, which form a partof this specification.

My invention relates to numbering ma chines ot that class in which aseries of disks with numbers on their peripheries are mounted upon anaxle supported in a head or yoke, so as to rotate automatically; and myinvention consists of a certain improvement in numbering machines, whichwill be fully understood by the following` description and claim.

In the accompanying drawings, Figure l is a front View of anumbering-machine with my improvements thereon. Fig. 2 is a side viewofthe same. Fig. 3 is a bottom View, showing the face ofthe lines orother marks on the left hand of units. Figs. 4 and 5 are detached views,better illustrating the adjusting devices. Fig. 6 is a View of a line ofprinting, showing one unit and the places to the left filled out.

In applying my improvements to numbermachines, I arrange a series ofdisks, A, B, C, and D, (more or less,) on a stationary axis or bar, E,held in place by a suitable key, e. These disks are arranged to rotateon the bar E by means of the handle F, in the usual manner. As I make noclaim to the general construction and operation of the numberingmachineno detailed description of the same is necessary. Therefore I nowproceed to describe nIy improvement.

The disks B C D, Ste., are made with a line of type thereon for printinga short line between 0 and l on the several disks, except the first orunits disk, for the purpose of filling the blank spaces in tens andhundreds, while printing units in numbers. These lines or othercharacters to fill blank spaces will prevent a printed number, eithertens, hundreds, Sto., from being changed after the printing is done bythe insertion of some (Model.)

number or digit in the place left blank in ordinary machines. A star orother character will obliterate the blank just as well as a line, (Seenat M, Fig. 6.)

In beginning to print a series of numbers I place the right-hand or unitdisk (seen at A in Fig. l) so as to print from l to 9, and the firstimpression of said disk will print the unit 1. The other disks, B C D,or tens, hundreds, and thousands, are set the halfnoteh, so as to bringthe lines or dashes M of these disks opposite to the unit l on the diskA, so the first impression will give us the result or impression shownin Fig. 6, the places of tens, hundreds, and thousands being canceled oroccupied by the lines or dashes M, and thus leaving no blank paper to beafterward im properly filled with significant figures. All the disks,except the first, are at first set on the dash, but never afterward stopon the dash, but in printing pass directly from 0 to I. After themachine runs on and has printed the units up to 9, inclusive, the disk Bmoves in the usual Inanner and brings the type l ot'said disk into tensplace, while disk A brings the cipher (O) into line to print theimpression l() from the two disks A and B, while the disks C and Dcontinue to print the lines or dashes M, as before, thuscanceling thespaces for hundreds and thousands. In like manner the machine ornumbering-head proceeds with printing higher numbers.

Having described myinvention, what I claim In a numbering-head,thecombination, with the bar or spindle and rotating mechanism, of a seriesof rotating disks having the usual series of iigures,from 0 to 9,inclusive, arranged at equal intervals and (except the unit-disk) adash-line or other stamping character inter'- Inediate between figures land 0, as described, whereby the disk may print the figures scfrt'rttt'mwithout regard to the dash, but when set byhand on the half-notch willprint the dash or other stamping character, substantially as described.

In testimony whereof I affix my signature roo in presence of twowitnesses.

WM. ROBINSON.
